Good evening. Tonight, I'd like to update the American people on the international effort that we have led in Libya - what we have done, what we plan to do, and why this matters to us.
I want to begin by paying tribute to our men and women in uniform who, once again, have acted with courage, professionalism and patriotism. They have moved with incredible speed and strength. Because of them and our dedicated diplomats, a coalition has been forged and countless lives have been saved. Meanwhile, as we speak, our troops are supporting our ally Japan, leaving Iraq to its people, stopping the Taliban's momentum in Afghanistan, and going after al Qaeda around the globe. As Commander-in-Chief, I am grateful to our Soldiers, Sailors, Airmen, Marines, Coast Guardsmen, and their families, as are all Americans.
For generations, the United States of America has played a unique role as an anchor of global security and advocate for human freedom. Mindful of the risks and costs of military action, we are naturally reluctant to use force to solve the world's many challenges. But when our interests and values are at stake, we have a responsibility to act. That is what happened in Libya over the course of these last six weeks.
Libya sits directly between Tunisia and Egypt - two nations that inspired the world when their people rose up to take control of their own destiny. For more than four decades, the Libyan people have been ruled by a tyrant - Moammar Gaddafi. He has denied his people freedom, exploited their wealth, murdered opponents at home and abroad, and terrorized innocent people around the world - including Americans who were killed by Libyan agents.
Last month, Gaddafi's grip of fear appeared to give way to the promise of freedom. In cities and towns across the country, Libyans took to the streets to claim their basic human rights. As one Libyan said, "For the first time we finally have hope that our nightmare of 40 years will soon be over."
Comment: A knee jerk reaction, or pre-planned?
